Just some extra parts I have laying around from when I had my eclipse. Never got to using them but I did buy them on here from other members.
Star Intercooler- Some denting on bottom but told it doesnt affect performance. $75+shipping
Star Log Manifold- Looks like it was welded at the one corner, other than that should be good for a budget build. 85+shipping.
JAW DIY wideband- Still in the original box I had it shipped in. Just never got around to it. Pretty sure all you need is a custom box to place it in. $60 shipped
